Specification of Letters Patent.

Patented July 15, 1913.

Application filed October 1, 1912. Serial No. 723,295.

To all whom it concern:

Be it'lmown that l, VViLLiAM A. FAIR- nU1iN,'a citizen of the United States, and resident of Short Hills, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements'hin Matches, of which the following is a specitication.

This invention relates to that type of match wherein the head is composed of a bulb of combustible and flaming material, non-igiiitible by friction on any ordinary friction rubbingsurface, and a tip of a composition ignitible by friction cn any such surface, the said bulb being of high heating and flaming character and serving as a vehicle to transmit the flame from the tipVY to the match splint and also being designed to prevent lateral rubbing contact of the ignition tips with each other or with the sides of the box in which the matches are contained. In such matches when the tip is composed of an ignition composition free from white phosphorus, and employing an oxidizing substance as an ingredient, a priniary'ignition tip of comparatively large size is required in o'rder to produce, When .it is lighted, a sutlicieiit body of flame to ignite the bulb smoothly and unliesitatingly. Thus the tips of the matches are apt to project to or beyond the sides of the bulbs, and by coming in rubbing Contact with each other defeat the safety purpose of the bulbs. Moreover, from the point of economy in manufacture such tips of large size are objectionable.

To provide a match wherein the primary ignition composition, free from white or yellow phosphorus, may be economically employed, and yet the ame be eiciently transmitted therefrom to the bulb without liability of a double or intermittent flare, is-

. the object of my invention; and to that end,

the linvention comprises a match having a head in which is provided between a relatively small tip and the bulb, a thin layer of combustible transmission composition which iS rapidly heated and easily ignitible by the il me from the tip, ,and at the same time q. ickly generates suliicient heat with flame td effect and insure the easy and prompt ignition of the bulb, as will be hereinafter described and claimed. n l

Alln the drawing, which illustrates a sec-` tional elevation of my improved match as enlarged, a, designates the splint and b ,the

head. This head comprises a bulblike mass erated by the tip, and at the same time produces sufficient heat and volume of flame to ignite the bulb easily and smoothly. AHence When the primary ignition tip is frictionally ignited uniform and easytransmission of t-he flame therefrom to the bulb, through the medium of the intermediate layer of composition, is effected.

Any known or approved composition for the bulb may be employed, suoli, for example, as zinc oxid, chlorate of potash, ground glass, plaster and glue, combined in suitable proportions. The end of the splint, prefer.- ably treated with parai'ln in the usual inanner, is dipped into this composition to pr'oduce the bulb l. l/Vlien this bulb has set or hardened its outer end is dipped into oi' otherwise coated with an ignition composition to produce the` transinission layer 2, which latter ccipt Vion is preferably such as is commonly used for the production of match heads designed to strike only on a specially prepared surface which is usually appliedA to the exterior of the match box. Any known or approved match head composition of this character may be employed, such, for example, as nthiosulfate of lead, chlorate of potash, ground glass, sulfur, amorphous phosphorus, kieselguhr and glue, combined in suitable proportions. The thin layer of composition can be readily ignited by a very small'ame; and in virtueV of its high heating character the layer, when so ignited, readily fires thebulb.

The primary ignition tip 3 on the layer is composed of a small quantity of match coni- 'position free from White phosphorus as above-mentioned. This tip can be readily ignited by friction on any ordinary friction rubbing-surface, and when so ignited its llame immediately attacks and ignites the composition of the contiguous layer 2. Any known or approved strike-anywhere match cmnpositiom'free from white or yellow-phos phorus and containing oxidizing material, may be employed for the tip, such, for example, as scsquisuld of phosphorus, chlo rate of pota-sh, zinc oxi'd, ground glass, plaster and glue, combined in suitable propel tions. v y

It will be seen that the provision between the primary ignition tip and the bulb, of the layer of match composition described, permits the use of a very small quantity of composition or the tip, thuslnot only resulting in economy of manufacture, but also obviating any liability of lateral contact of the tips with each other or withv the'sides of the box in which thematches' are contained.

claim- 1. As a new article of manufacture, a match having a head composed of a bulb of combustible and iiaming material, n0n ignitible by friction on any ordinary friction rubbing-surface, a thimllayer of composition on said bulb, non-ighitible by ordi'- nary friction except on afspcially prepared rubbin surface, and a primary ignition tip on sai layer ignitiblebf7 friction on any ordinary friction rubbing-surface, whereby when the tip is ignited the flame will be smoothly transmitted therefrom with increasedrvolume to the bulb. A

2. As a new articletif-manufacture, a

'match having a head2 composed of a bulb of combustible and flaming material, nonignitible by friction on any ordinary ric tion rubbing-surface, a primary ignition tip ignitible by friction on any ordinary friction rubbing-surface, said tip being free of white phosphorus and containing an' oxidizing material, and a .thin layer o composition of high heat-ing character betweenthe tip and the bulb-z, said composition being nonignitible by side friction of the match heads.
